R Program to take input from the user and display the values

How to take input from the user and display it


Here we are explaining how to write an R program to take input from the user and display that values. we can use the readline() function to take input from the user (terminal). Here the prompt argument can choose to display an appropriate message for the user. In this values are displayed using print with argument R.Version.string which returns a list with character-string components.

How user input reading is implemented in R Program


We are using readline() function for taking the user's input. Given below are the steps which are used in the R program to read and display values. In this R program, we accept the user's values into name and age by providing an appropriate message to the user using 'prompt'

ALGORITHM


STEP 1: prompting appropriate messages to the user

STEP 2: take user input using readline() into variables name, age

STEP 3: print the user input along with other text. 

STEP 4: use R.Version.string for returning list with character-string components

 

R Source Code

                                          name = readline(prompt="Input your name: ")
age =  readline(prompt="Input your age: ")
print(paste("My name is",name, "and I am",age ,"years old."))
print(R.version.string)
                                      

OUTPUT

Input your name: Jhon
Input your age: 23
[1] "My name is Jhon and I am 23 years old."
